I am running exchange 2007/outlook 2003. We have several calendars under public folder. I am the exchange admin. There are few calendars that were created by users via outlook. I am now trying to modify permission on them. When I right cllick and go to properties, I only see general, home page, and summary tab. I do not see administration, forms and permissions tab like I am able to with some other calendars. I am tying to take ownership of all these calendars and be able to control permission, either via outlook or exchange console. Any advise is appreciated.
